Digidesign Mbox 1 [Mbox]

[filmtools]

I have a Digidesign Mbox 1 [Mbox]

Bus 005 Device 005: ID 0dba:1000 Digidesign Mbox 1 [Mbox] under CentOS8
I have used the flashing tool on OSX from http://www.zamaudio.com/?p=953 to fix white noise and its gone now.

Sound card is working really great and clean - but I have to keep the settings - sound panel open under output. If I close this after few seconds
sound card goes mute.

Thanks,
Ed
